For number 3, it is reciprocal
and for number 4, it is whole number
When x is 3, y is 4
To do this, go to the right 3 units and go up until the line intersects with a grid point
At three, y is 4
Hope this helps!
You could use the equation y=mx+b
Find the slope of the two coordinates. I would personally suggest using stack and subtract:
(0,2) 2-5 -3 3
(2,5) -------= ------= -----
0-2 -2 2
We have the slope but we need to find the y-intercept.
y=3
--x+b
2
Plug one of the coordinates in the constructed equation above:
2=3
-- (0)+b
2
2=0+b
-0=-0
------------
b=2
We found the slope and y-intercept. Now we have our complete equation. The equation is:
y=3
--x+2
2
Have a blessed day!
Answer: 
Step-by-step explanation:
Given: 
and 
To find : (f o g) (10)
For this we first find (f o g) (x)= 
Now,
Hence, the value of
Answer:
x=8.94 ; y = 1.58; z=2.02
Step-by-step explanation:
solve 10x+4y+12z = 120 → 5x+2y+6z = 60
8x + 2y +32Z = 160 → 4x+y+16z = 80
To eliminate z multiply first equation by 16 and second equation by 6.
80x+32y+96z = 960
24x+6y+96z = 480
on subtractionwe get 56x+26y = 480
dividing by 2 we get, 28x + 13y = 240
Now we have a given equation 11x + 77y = 220 → x + 7y = 20
solving 28x + 13y = 240 and x + 7y = 20
28x + 13y =240
28x + 216y = 560
subtracting we get, 203y = 320
y = 1.58
x = 8.94
z = 2.02
